Acebeam Rider RX Titanium Flashlight Review

Acebeam Rider RX Titanium Flashlight Review

I liked my stainless Acebeam Rider Rx flashlight so much that I bought one in titanium. It’s basically the same, but fancier! Read on!


Official Specs and Features

Here’s a link to the Acebeam Rider RX Titanium flashlight product page.

Versions

There are quite a few versions by this point. There are four finishes of this metal (which I believe is stainless steel with the internal blue part being aluminum.) Acebeam also offers this stonewashed titanium version (seen in this review).

I believe all these have the same emitter and are otherwise identical internally.

Price

The titanium version seen here is listed on Acebeam’s site at $59.90 (that’s a ShareaSale link). You can find them on Amazon too!  Here’s my referral link to Amazon. It’s noticeably less expensive at Amazon, coming in at $45.04.


Short Review

I really liked the other version I already reviewed. This titanium version at $45 is a great deal! The build quality is great, and it accepts both AA (1.5V) and lithium-ion (4.2V) cells.  Despite being “into” fidgety things, the pocket clip fidgetiness does not actually do anything for me. It’s neat, but not something I’ll use.  The output is great from both a numbers perspective and from a CRI and CCT perspective, too.  I’m very pleased with this light.

Build Quality and Disassembly

Acebeam Rider RX Titanium flashlight

Build quality on the Acebeam Rider RX Titanium flashlight is great, as you’d probably expect from Acebeam. The outer shell (the silvery part) is made of titanium. That blue inner sleeve is aluminum.  There are also copper parts in here.

When the light is in the extended format (which is how you’ll swap cells), the switch is not accessible.  Also below you can see where the moveable pocket clip moves to. There are three detents that latch into place very pleasantly and positively. They provide a fidgety amount of resistance and do in fact slide around very nicely (when you want them to do so).

The pill, seen below, is copper. Because they’re copper, they are uncoated but still smooth.

The negative end gets a spring. The positive end has just a button.

My review version has a bit of unfortunate discoloration in the titanium. You can see it clearly in this photo – the right third is a darker color, with a very clear split defining the two colors.

Size and Comps

Size:95.7mm x 18.6mm x 26.1mm
Weight:69.5g

If the flashlight will headstand, I’ll show it here (usually the third photo).  If the flashlight will tailstand, I’ll show that here, too (usually the fourth photo).

Here’s the test light with the venerable Convoy S2+.  Mine’s a custom “baked” edition Nichia 219b triple.  A very nice 18650 light.

And here’s the light beside my custom engraved TorchLAB BOSS 35, an 18350 light.  I reviewed the aluminum version of that light in both 35 and 70 formats.

Retention and Carry

As covered above, there’s a pocket clip included and attached. This clip is held in place by two screws and is thus very secure.

When in the resting state, the pocket clip has a little groove to rest in. When in the extended state, there is no groove. This version (the titanium) ships with a little patch. This might be just intended for shipping purposes, but it’d be reasonable to leave it in place to protect the titanium. That said, on this version, the pocket clip doesn’t even touch the body anyway.

The pocket clip is the crux of the fidget factor on the Acebeam Rider RX flashlight and can be twisted around and then pushed forward for use as a fidget toy.

This actuation is also necessary for swapping the cell. Otherwise, the head is inaccessible. And when the body is extended (or the sleeve is pulled back?), the tailswitch becomes nearly inaccessible.

There’s also a lanyard included. That lanyard attaches to the pocket clip. Because the pocket clip is screwed on, and the lanyard attaches through a hole, this lanyard attachment is very secure.

Power and Runtime

Included with the Acebeam Rider RX titanium flashlight is a lithium-ion 14500 cell. However, the Rider RX will also run on a single AA cell, too (that is, a 1.5V cell – primary or NiMH.)

The included 14500 cell is a standard button top, with a capacity of 920mAh.

The cell goes into the light in the usual orientation: button (positive end) toward the head.

Performance with the 14500 cell is good, and there seems to be reliable low voltage protection.

I also tested the highest two levels with a NiMH, as mentioned above. Output with a NiMH is lower than the 14500 cell.

Overall I’d say performance is good, and I really appreciate that the Acebeam Rider RX flashlight runs on both lithium-ion and 1.5V cells.

Charging

While the Acebeam Rider RX flashlight itself doesn’t have built-in charging, the included cell does. That’s USB-C charging, and the port can be seen below.

Acebeam includes a short USB to USB-C cable.

Here are a few charge cycles.  Charging looks fine, but is a bit slow at around 0.5C.

C to C charging works fine but is no faster than USB to USB-C.

Modes and Currents

Pulse Width Modulation

Every mode from both cell types uses PWM. It’s not at all bad PWM though, and I don’t find it the least bit noticeable.

AA:

14500:

For reference, here’s a baseline shot, with all the room lights off and almost nothing hitting the sensor.  Also, here’s the light with the worst PWM I could find.  I’m adding multiple timescales, so it’ll be easier to compare to the test light.  Unfortunately, the PWM on this light is so bad that it doesn’t even work with my normal scale, with is 50 microseconds (50us).  10ms.  5ms.  2ms.  1ms.  0.5ms.  0.2ms.  In a display faster than 0.2ms or so, the on/off cycle is more than one screen, so it’d just (very incorrectly) look like a flat line.  I wrote more about this Ultrafire WF-602C flashlight and explained a little about PWM too.

User Interface and Operation

A single switch controls the Rider RX.  This is a mechanical tail switch and has a nice big metal (“probably metal”) switch cover.

The switch is quite proud, but with enough determination, the light will tailstand.

As you can see below, the action is quite deep. When depressed (or “on”) the switch does rebound. That is to say, it doesn’t stay flush with the steel body.

Here’s a UI table! The user interface for either cell type is the same.

LED and Beam

In the Acebeam Rider RX flashlight is a single Nichia 219f emitter. This is my first experience with the 219f, and I’m happy with it. Acebeam opted for the 5000K High CRI (90) version.

That emitter is paired with a smooth and not all that deep reflector.

LED Color Report (CRI and CCT)

As stated above, Acebeam calls this a 5000K, CRI90 emitter. I’m happy to report that mine seems to be warmer than 5000K (around 4600K-4800K, depending on the mode) and at or above 90 CRI for every mode.

Tint vs BLF-348 (KillzoneFlashlights.com 219b version) (affiliate link)

I keep the test flashlight on the left, and the BLF-348 reference flashlight on the right.

The 14500 output is noticeably brighter than the AA output, and the photos below adequately demonstrate that. The AA output is still quite usable though.

I compare everything to the KillzoneFlashlights.com 219b BLF-348 because it’s inexpensive and has the best tint!

Conclusion

What I like

  • Attractive light
  • Neat fidgety factor
  • Nichia 219f seems like a great emitter (high CRI, good CCT)
  • Complete package
  • Runs on both lithium-ion and AA (alkaline and NiMH) cell types
  • Very simple user interface
  • Great price point

What I don’t like

  • I don’t actually care about the fidget factor on this light. It’s neat but I won’t use it that way.
  • The pocket clip not touching the body makes it a bit loose in carry
